Sometimes the result that I get is 0 and it is impossible. Is there any code for doing it? with the code entropy() the result is 0

A first search on the FEX turned up this entry, and you can check out this entry as well.

Post your image where you get zero. If it's a uint8 image, try casting to double() before sending it into entropy().
